10 Claims.

Our invention relates to improvements in side register gauges for printing presses, this application being a division of our copending application, Serial No. 649,567, filed December 30, 1932.

An object of the invention is to provide a simple and durable side register mechanism for bed and platen presses adapted to be readily adjusted during press operation.

Another object of the invention is to provide registering mechanism, as above, adapted readily to be used for both right and left register.

A further object of our invention is to provide a sideregistering mechanism for a bed and platen press in which a sheet shifting member is carried bythe moving platen and a second member, for operating said first member, is mounted on the press frame and adjustable as the platen moves.

With the foregoing and other objects in View, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.

In the drawings, Fig. l is a vertical sectional view of a bed and platen press equipped with a form of our improved side register mechanism, the structure thereof being shown in side elevation; Figs. 2 and 3 are rear elevational views in detail of the press platen and adjacent frame structure, said views also showing the side register mechanism in detail, an adaptation of the gauge mechanism for register in one direction being shown in Fig. 2 and an adaptation of the gauge mechanism forregister in the opposite direction being shown in Fig, 3; Fig. 4 is a detail sectional view taken on line 4-4 of Fig. 3, and Fig. 5 is a detail sectional view taken on the line 55 of Fig, 3.

Reference being had to the accompanying drawings, it will be-seen that the press structure shown includes a frame 30, a. platen rocker 3B thereon and a platen 39 carried by said rocker. A suitably driven gear cam wheel 36, mounted on a shaft 31 in the press frame 39, imparts an oscillatory movement to the platen rocker 38 in the customary manner, said gear cam wheel being sheathed by a gear guard I99 incorporated in the press frame structure. A bed 44, supported by legs 46 pivoted on a bed shaft 41 mounted in the frame 30, is connected with the gear cam wheel 36 by means of a side rod 5i, a second and similar rod (not shown) being also employed, in the usual manner, to connect said bed with a crank wheel (not shown), mounted on the shaft 31. In its oscillatory movement, the platen 39 tips back and forth from open position to (Cl. i 414) I impression position, such movement of the platen being accompanied by a relative movement of the bed 44 which brings a form therein against the platen, in its impression position and retracts the bed from the platen in the open position of the latter. i g

The illustrated side register mechanism includes a rod IB Z mounted to slide lengthwise along the lower edge of the platen 39 in bearings I 83, I84 secured to the platen, said rod being feathered in bearing I33, as shown, and thereby deprived of rotational movement in said bearings. A roller I85 journaled on the end of the rod I82, at the right hand side of the platen, rolls up and down along an arcuated rail I86 as the platen 39 opens and closes, said roller I85 being yieldingly held against Said rail I86 by means of an expansion spring I81 coiled about the rod I82 and compressed between the bearing I84 therefor and a thrust collar I88 secured to said rod. The rail I86 is pivotally mounted medially thereof on a stud I89 projecting from the gear guard I99 and may be angularly swung with respect to the path of movement of the platen 39 from the one of its extreme positions shown in Fig. 2 to the other of its extreme positions shown in Fig. 3. The curvature of said rail I86 is that of an arc struck from the axis about which the platen 39 rocks and the bearingsurface I88 on said rail for said roller I85 is a plane surface. A. push-pull adjusting screw I94. journaled in a bearing I95, pivoted by means'of a pintle I94 to the gear guard I90, is threaded in a nut I94 pivoted on an extension I9I of the rail I86. This push-pull screw I94 is turnedby means of a finger piece I94, which abuts against one side of the bearing I95. Securedto said screw I94 and abutting against said bearing I95 at the other side thereof is a thrust collar I94? As a preliminary measure, this adjusting screw I99 is manipulated to secure, roughly, the desired angular adjustment of the rail I86 and is further manipulated, during the operation of the-printing press, to secure finer adjustments of said rail. a

For rigidly securing the rail in its various angularly adjusted positions, the extension I9I is formed with a head I92 having a curved slot I92 therein, the curvature of said slot being that of an arc struck from the axis of the stud I89 upon which the rail is pivotally mounted. A set bolt I93, threaded in a boss 193* on the gear guard I99 and received in the slot I92 of said extension head' I92, is employed to releasably clamp the'extension I9I relative to the gear guard I90 and thereby rigidly hold the rail I86 in its adjusted positions.

A gauge I96 for right register, and of the construction shown in Fig. 2, may be employed by mounting the same on a block- I9'I slidably adjustable on the rod I82. This form of gauge has a shank portion l96 paralleling the rod I82 and an arm I96 issuing from said shank portion at right angles thereto. Said arm is slotted, as at I96", and is equipped with the usual slidingly adjustable sheet engaging finger I96 A gauge I96 for left register, as shown in Fig. 3, may also be mounted on the adjustable block I91, or the well known type of swinging tongue may be employed and operated by the reciprocating rod I82 for engaging a sheet on the platen and shifting it into register.

For right register, as viewed from the front of the press, the gauge I96 and rail I86 will occupy positions, for example, as shown in Fig. 2, while for left register the gauge I96 and rail I86 will occupy positions, for example, as shown in Fig. 3, the position of the rail I86, in either case, being readily adjusted through the medium of the adjusting screw I94 during the operation of the printing press.

Changes in the specific form of our invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of our invention.
